HEEL-sHArING MACHINE.

lApplication filed September 24, 1924. Serial NO. 739,615;

This invention relates to. machines for shaping heels and more particularly to machines for trimming the periphery .as distinguished from the breast of a heel. In

4some respects the invention is more particularly concerned with machines in which a profile of predetermined curvature is Vimparted to the periphery of the heel byna cutter having that profile. y i

In nearly all, if not quitea-ll,` cases a heel that has a curved profile also has a wedge factor, the latter consisting in a pitch or inclination of the base surface' relatively to the tread surface, in consequence of which the heel has greater height at the back than at the breast. It may therefore be stated as a general rule thata` curved profile is accompanied by a Wedge factor, and exceptions to this rule, if any, may be disregarded for purposes of discussing thepresent invention. Louis heelsCuban heels and military heels are common examples of heels having curved profiles and more or less of a Wedge factor. In shaping the peripheries `of such heels it has heretofore been the practice to do it by two successive trimming operations, by the first of which vthe body of the heel is shaped and by the second of which the wedge-shaped portion is trimmed. l-leretofore no machine capable of shaping the entire periphery in one operation in such a way as tocompensate for the wedge factor and at the same time produce a heel of the desired shape has gone into general` use.

.lt has been proposed to solve this problem by equipping a heel-trimming machine with a movable topliftguard as well as a movable rand-crease guard, and toprovide means operable by the operative to shift said guards lengthwise o f the profile4 of the cutter while the latter is operating, upon a heel. This proposed construction forms the subject-matter of Letters Patent of the United States No. 1,513,804, granted Norl vember 4, 1924.-, upon an application of Frank A.. Eich, and in that case the prob'- lem of covering and uncovering a portion of the trimming cutter to compensate for the graduated height of the heel, caused by the wedge formation, is solved by mechanism operable manually and independently to shift the toplift guard as the shaping operation progresses. s y i y In View of the above-mentioned*problems and conditions, an object of the present invention is to provide an improved heel-shapingy machine by which a heel having a Wedge factor may be shaped with a curved profile in a single operation without dependence upon skill, judgment or special effort on the part ofthe operative to compensate for the wedge factor. y

A feature of the invention consists in a heel-shaping machine having a movable top lift guard and means operable by the shoe for shifting said guard heightwise of the heel to various positions.

lVhen a cutter having a curved profile is used to shape the entire height of a wedge heel in one operation it is necessary, if the curve Vis not uniform, to change the relative positions of the cutter and the toplift guard as the trimming progresses around the heel, so that the guard will cover and uncover certain portions of the cutter according to the particular point of the heel on which it is operating. This necessity is `most marked in the case ofl a Louisheel, since, if the sharply curved portion of the cutter that is used to shape the'backof the heel is used also in its entirety to trim the sides, it will cut so deeply as to strike the heel nails and `to malte the heel too narrow in the waist. Consequently, the yabove-mentioned feature of the present invention is preferably embodied in mechanism operable by the turning of the shoe to shift the toplift guard asl aforesaid so that it will cover a portion of the cutter when either side of the heel is presented to the cutter and will uncover that .portion gradually and progressively as the trimming the heel fromthe, breast to the back. Conversely, the shifting mechanism is also preferably constructed to cause the guard to cover that portion of the vcutter gradually and progressively as the trimming progresses along the opposite side of the heel from the back toward the breast.

`In anothenaspect,the invention consists in an Organization comprisingrtwo movable heel-engaging membersfor example, a toplift guard and aheel-rest, and mechanism operable by the shoe to shift said members relatively to each other according to their individual requirements.

y Another'feature of theinvention consists in the provision,` in an Organization such progresses along one side ofv as that above indicated, of a spring-stressed rand-crease guard normally urged toward the toplift guard and adapted to yield in the. opposite direction according to variations in position ofr the toplift guardv and in response to the demandsl of the wedge factor' of the heel. Thus, in opeiation, the heel is positioned heightwise, thatis, lengthwise of its axis of turning, by its own turning movement about such axis, through the agency of a movable toplift guard, while the randcrease guard automatically follows the pitch and shifting of the rand-crease.

To utilize the turning movement of the shoe for the purpose of shifting the heel-positioning member as aforesaid, the invention provides a follower' formed to embrace the shoe and arranged to swing about an axis substantially parallel to the height or axis of the heel, and means operable by said follower to produce the desired shifting move ment of said heel-positioning member.

Another object of the invention is to provide. in a heel-shaping machine, a movable heel-rest and mechanism operable by the shoe for shifting it as successive points along the periphery of a heel are presented to the critter'. In heel-shaping machines it is customary to provide a heel-rest arranged to engage the periphery1 of the heel to sustain the latter against the cutting stress of the cutter. By reason of the irregular contour of a heelV the turning movement produces a bodily7 movement relatively to the heel-rest, and this relative bodily movement, when the heel-rest is stationary, as in prior construe tions, shifts the theoretical tangent between the cutter and the heel. I have found that it is desirable to maintain this tangent at a fixed point, or nearly so, to keep the working conditions more nearly constant.

Accordingly another feature of the invention consists in a movable heel-rest arranged to sustain the heel against the cutting stress of the cutter, and means, preferably operable by turning the shoe, for shifting the heelrest to maintain the tangent of the cutter and heel at a fixed point or as nearly so as the irregular contour of the heel will permit. According to this feature the movement of the heel-rest compensates for the irregular contour of the heel.

Another object of the invention is to provide for maintaining the point of contact between the heel-rest and the heel in one plane with regard to the height of the heel, that is, at a constant distance from the plane of the tread surface, notwithstanding the heightwise movement imparted to the heel by the tonlift guard.

Accordingly another feature consists in an organization in which the heel-rest partakes of the shifting' movement imparted to the loplift guard in addition to the aforesaid movement imparted to the heel-rest exclusively. Thus, while the turning of the shoe imparts a simple shifting movement to the toplift guard it also imparts a` compound shifting movement to the heel-rest.

Other features of the invention are here inafter described and claimed and are illustrated by the drawings.

Referring to the drawings,

Fig. l is a front elevation ol' the upper portion of a heel-shaping machine constructed in accordance with this invention;

Fig. 2 is a vertical section through the structure intersectcd by line llt-II of Fig. l;

Fig. 3 is a perspective view including the rotary cutter-head, the guards and the heeliest, and mechanism operable by the shoe for shifting one of the guards and the heelrest;

Fig. 4 is a horizontal section through thc Structure intersected by line IV-IV of Fig. 2;

Fig. 5 is a top plan view ot' the asseinblage shown in Fig. 4 with the addition of portions of the cutter-head, heel-rest and other parts;

Fig. 6 is a front elevation showing a heel in three successive positions and the heelN rest in three corresponding positions; and

Fig. 7 represents the cuttenhead conventionally in end elevation and includes the heel-rest and the outline of that portion of the heel that contacts with the heel-rest in three successive positions corresponding to 1 those represented in Fig. 6.

The framework of the machine, so far as it is illustrated in Fig. l, comprises bear ings 10 and 12 in which a shaft 14 is journaled. This shaft carries a cutter-heagl coinprising two cutting blades 16, 16. The cutting edges of the blades have a profile designed to impart the desired shape or style to the heel 18 which, in the present instance, is a Louis heel. The shaft 14 also carries a pulley 2() on which a driving belt (not shown) is intended to run.

A toplift guard 24, a counter guard 26 and a heel-rest 28 are arranged to assist the operative in maintaining the heel in the desired relation to the cutter-head, each of said guards being effective, as usual, to control the depth of trimming. In the illustrated machine, both the toplift guard 24 and the heel-rest 28 are mounted to be shifted during the progress of the heel-shaping operation, as will be explained.

The most common mode of manipulation to shape a heel is to start at the left-hand side and progress around the back to the right-hand side b v turning the heel in the direction indicated by an arrow in Fig. 7. Thus, the shoe occupies initially the position represented by broken lines in Fig. 3 and the operator turns it by grasping the forepart with the right hand and swinging the toe from top to bottom, meanwhile using the left hand to .steady the heel part and main'- tain the counter and toplift against the counter guard 26 and toplift guard 24, respectively.

The elements A, B and C in F 6 represent the heel in three positions which arer respectively the initial position, the median position and the inal position. In Fig. 7 the elements a, 7) and c represent the contour of that portion or cross-section of the heel that engages the heel-rest 28. and the three positions correspond respectively to those represented in Fig. 6. Figs. 6 and 7 also show three positions of the heel-rest 28, said positions being numbered l., 2 and 3 respectively and corresponding to the three posi,- tions of the heel. y To utilize the turning movement of the shoe to shift the heel-rest progressively as the shaping of the heel progresses, the machine is provided with a follower arranged to .swing about a horizontal axis substantially parallel to the height of the heel, said `follower having parallel arms 30, `30 arranged to stradd-le the forepart of the shoe, as shown in Fig. 3. The swinging movement of this follower is utilized also to shift the toplift guard 24 to various positions, as hereinafter explained. y

The follower comprises, in addition to the arms 30, 30,- a block 32 and an arm 34.

`The two arms 30, 30 extend through a hole in the block 32 and are fastened by a setscrew 36. Those portions of the arms that extend through the block are semicircular in cross-section and each is a counterpart of the other` which formation enables a single set-screw 'to bind botharms and at the same time provides for adjusting the arms toward and from each other according to the width of the shoe to be straddled. The block is also bored for the reception of a cylindric portion of the arm 34 and is providedwith aVset-screw 38 by which it may be fastened at various positions with regard to the length of the shoe.

The arm 34 is fixed to a horizontal shaft 40 (Fig. 4) which is journaled in a fixture 42 fastened to or forming a part of the main frame of the machine. A wrist-pin 44 ihaving a spherical head is carriedby the hub of the arm 34 and is connected Vto an` arm 46 (Fig. l) by a connecting link 48. The connection between the link 48 and the arm 46 is a ball-andsocket connection 45 similar to that between theelink and the arm 34. The arm 46 is rigidly connected to aspur gear segment 50 by a horizontal shaft 52 (see Fig. 2), said shaft being journaled in a boss 54 onthe under side of a movable structure 56. The segment 50 meshes with a segment 58 formed on an arm 60, said arm being carried by the movable structure 56 and connected thereto by a pivot 62. The

arm 60 carries the heel-rest 28. The motions of the parts in this train of mechanism are as follows The follower 30, 30 swings about the axis of the horizontal .shaft 40, and the wrist-pin 44,- being eccentric to said axis, is

carried bodily about the latter. Thus, the wrist-pin moves the link 48 up and down to rock the arm 46 and the horizontal rock.- shaft 52 to which said arm is fixed. The gear segment 50, being fixed to this rockshaft, also pai-takes of this rocking movement and imparts a corresponding rocking movement tothe arm 60 which rocks on the horizontal pivot 62 and 'carriesthe heel-rest 28 up and down. The train of connections just described is such that by swinging the follower comprising the arms 30, 30 to. its upper position, as shown by Fig. 3, the heelrest 28 is moved toits lowest position indicated by the numeral l in Figs. 6 and 7, and by swinging the follower to its lowest position shown in Fig. l, the heel-'rest is shifted to its highest position, indicated at?) in Figs. 6 and 7. The intermediate position 'of the heel-rest, indicated at 2 in Figs. 6V and 7, corresponds to the median position of the follower. Y

As shown by Fig. 4, a cam 64 ispinned to the arm 34. The function of this .Ica-m is to shift the toplift guard and the heel-rest horizontally, and the motion produced tl1ereby causes the toplift guard to cover and un cover certain portions of the trimming blades 16, 16 during the heel-shaping operation...

The cam 64 acts upon a rolly 66 mounted in a carriage 68. This carriage is arranged t( slide on the fixture 42 and has Hange-andgroove connection therewith, as shown in Fig. 2. A compression spring 70 is arranged to maintain the roll 66 against the cam 64 and to shift the carriage from left to right undercontrol of the cam. The left-hand end ofthe spring 70 is seated against a portion ofthe fixture 42 while the right-hand end is seated against an abutment 72 car-- ried by the carriage 68. i The toplift guard 24 is affixed to the movable structure 56 and the latter' is pivotally,coni'iected to the carriage 68 by trunnions 74. By means of these connections the cam 64 operates to shift the toplift guard andthe heel-rest horizontally,-

but the lines of motion are capable of being regulated, by means about to be described, to conform approximately to the profile of the cutters 16, 16, or at least to that portion of the profile with which the shifting movement of the toplift guard is coextensive.

As shown by Fig. 2, a stud 7 6 is fastened to the .fixture l42 and projects upwardly vthrough a slot in the carriage 68 andinto a slot 78 formedin a bushing` 80. Thisbushing is arranged in a socket formed in the movablestructure 56 and is adapted to turn about a vertical axis for purposes of're'gulation. set-screw 82 extends through a slot 84 in the bushing and screws into the element 56, so that when it is set down tightly its head binds the bushing against rotation. The slot 78 (Fig. 5) formed in the lower part of the bushing extends diametrically thereof but by adjusting the bushing about its axis the direction of the slot 78 may be altered within the range alforded by the slot 84. As shown by Figs. l, 3 and 5, the toplit't guard 24 covers a portion ot the cutter, and the profile of the portion so covered is inclined relatively to the axis ot the cutter shaft. Accordingly, the bushing 80 is adjusted to place the slot 78 at an angle corresponding to the inclination of that portion ot the cutter under consideration. ln other words, the slot 78 is nearly, if not quite, parallel to that portion of the profile ot the cutter which is within the range of travel of the toplift guard, so that as the toplitt guard is shifted from right to lett by the cam 64 and from left to right by the spring 70, its lines of motion will parallel the profile ot j the cutter.

Vhenever cutting blades ot' a different profile are substituted, a corresponding adjustment of the lines of movement of the toplift guard may be quickly effected by `loosening the screw 82 and turning the bushing 80.

The counter guard 26 is formed with a lip 86 to run in the rand-crease of the shoe and is mounted to be positioned by the shoe so that the lip 86may take whatever position is necessary to follow the rise and tall ot the rand-crease as in the case of a .shoe whose heel-seat is pitched or inclined relatively to the tread surface. As shown by Figs. l and 3, the counter guard is carried by a member having a stem 88, and said stem is arranged to slide in a fixture 90. A screw 92 is carried b y the stem 88 and projects through a slot 94 in the lixture to prevent the counter gua-rd from turning about the axis of the stem. A compression spring 96 nested in the fixture bea-rs against the inner end of the sleeve 88 to press the counter guard toward the toplight guard but permits the counter guard to move from right to lett in accordance with the demands of the randcrease.

In using the apparatus hereinbetore described the operative places the torepart of the shoe between the parallel arms 30, 30 and places the periphery of the untrimmed heel upon the rest Q8 and the periphery of the toplitt against a narrow lip 98 formed on the topliit guard to control the depth of trimming. Incidentally to thus manipulating the shoe preparatory to shaping the heel, he also catches the lip 86 of the counter guard in the rand-crease and swings the toe of the shoe to its upper position as shown by Fig. 8. `When the parts are in this position the heel-rest 28 is in its lowest position and the toplift guard is advanced to the lett as tar as it will go, thus covering that portion of the cutter that is to be uncovered gradually until the shaping has progressed to the extreme back of the heel. of the heel is now presented to the cutter so that the shaping will begin at the 'trent or breast.

The manipulation ot the shoe is substantially the same as that heretofore practised. It the arms 30, 30 have been adjusted to straddle the shoe at the ball portion the toe end of the shoe will project beyond them tar enough to be grasped by the right hand ot the operative. Vilhile using his left hand to grasp the heel part ot the slice, the operative swings the toe toward him and downwardly, and at the same time tilts the shoe as may be necessary to maintain the counter and toplilt against their respective guards. T he parallel relation of the arms 30, 30 provides for tilting the shoe in the manner just mentioned.

lVhile the shoe turns about the axis of the heel from its initial position to its median position (see B, Fig. 6. and b, Fig. 7) the toplitt guard moves :trom the left-hand limit of its range ot travel to the right-hand limit` thereby uncovering the maximum portion o t the cutter to trim theI back of the heel, but as the toe ot the shoe swings trom its median position to its final or lowest position, the toplift guard is shifted in the opposite direction, that is, from right to lett. In other words, the first position and the inal position ot the toplil't guard are identical while in its median position it is at the other end of its range of shifting movement. The work-rest 28, on the other hand, continues to move upwardly through the entire shap ing operation to maintain the working point as nearly as possible at a constant level. This may be understood by reference to Figs. 6- and 7, in which position l of the heel-rest is its initial position, position 2 corresponds to the stage when the point of trimming has progressed to the back ot the heel, while posi* tion 3 is the final position.

It is to be observed that the heel-rest also partakes ot the horizontal motion imparted to the toplift guard by the cam 64 and is thus maintained substantially in constant relation to the toplitt guard so tar as horizontal motion is concerned. Since the heel-rest partakes ot the horizontal motion of the toplift guard while it. receives a vertical movement, its motion be defined as compound, while that of the toplitt guard is simple. Furthermore, since the heel-rest and the toplift guard are both carried by the element 56, the horizontal component ot movement of the heel-rest will partake of the regulation aorded to the toplitt guard by adjusting the bushing 80.
